Broomfield, Colorado USA, May 18, 2005 - Expanding the boundaries of innovation in the waterworks industry, MWH Soft, a leading global provider of environmental and water resources applications software, today announced the worldwide availability of H₂ONET® Generation V6 for AutoCAD® 2006 (Autodesk, San Rafael, CA). The updated release debuts features that advance core database functions, delivering faster and more intuitive network modeling capabilities than ever before.

V6 marks the most significant milestone to date in the evolution of the company's flagship product, an industry standard for comprehensive water distribution engineering and the premier choice for major ENR design firms and large water utilities around the world. The release underscores MWH Soft's determination to be the leading provider of infrastructure modeling solutions for waterworks industry professionals working in the powerful AutoCAD environment. "MWH Soft developed an AutoCAD 2006-compatible version of H₂ONET just as we received the AutoCAD 2006 update, I applaud them for it," says Arnold Strasser, PE, Hydraulic Engineer with Denver Water in Colorado and an industry network modeling expert. "This is one of many testaments to the company's ongoing commitment to supporting their clients needs, and as always in a timely manner."

Built atop AutoCAD, the world's leading CAD platform, H₂ONET delivers breakthrough performance in integrated real-time network modeling, GIS data exchange, spatial database query and analysis across multiple data types, and the sophisticated mapping required for complete infrastructure (asset) management and business planning. Its pioneering functionality and state-of-the-art computational algorithms allow engineering professionals to directly access CAD and GIS datasets, extract pertinent modeling information, and automatically construct, skeletonize, load, calibrate, analyze, design, operate and optimize any network model - saving time and money across the enterprise. Such capabilities can greatly assist water utilities in complying with drinking water quality regulations, understanding and controlling taste and odor problems, developing cost-effective energy solutions for water system operations, improving system reliability and integrity, optimizing capital improvement and rehabilitation programs, enhancing community relations, and planning sound security measures.

"Our priorities have always been to advance the frontiers of modeling technology and support our customers' successes by making them more productive and competitive," said Paul F. Boulos, Ph.D, President and Chief Operating Officer of MWH Soft. "H₂ONET support of AutoCAD 2006 and dynamic database functionality is the latest move to deliver on our promise to equip customers with the ultimate decision support tool for water distribution systems. It is once again setting the standard for quality and high-end water network modeling and management with unrivaled cutting edge capabilities, rich functionality, speed, stability, and ease of use. From top to bottom, this release is designed to enable world-record modeling performance - allowing our users to increase productivity and quality while achieving their engineering and business goals."

"The sixth release of H₂ONET marks an important milestone for our company and our customers," said J. Erick Heath, PE, Vice President of Sales and Client Relations at MWH Soft. "What began as a software tool to help engineers and planners graphically represent and simulate their drinking water distribution systems has evolved into an innovative modeling and management solution that's used worldwide. Our customers have been extremely progressive in the ways they use H₂ONET, and we continue to advance this CAD-centric modeling platform to best serve their network management challenges. Today, H₂ONET is by far the best choice for comprehensive network modeling in the AutoCAD platform, from basic planning studies to sophisticated design, rehabilitation, expansion and operation projects."
